PVC Union Covers are thermoformed PVC covers designed to insulate pipe unions and connectors that protrude out past the adjacent pipe insulation.  Each PVC Union Cover comes with a rectangular fiberglass insert which is first wrapped around the union and then the PVC Union Cover is installed over the insulation.  PVC Pipe Union Covers are two piece fittings (comes in two halves) which are either tacked, taped, or glued together during install.  The two halves of the PVC Unions are designed to have a large overlap to allow easy install and hassle free adjustment to the outside diameter of the pipe insulation.

Installation Methods:

1.) Use serrated stainless steel King Tacks which are pressed through the overlapping pieces of the fitting cover and will hold them securely. (Steam, Hot Water, etc)
2.) Use PVC Vinyl Z-Tape to seal the fitting cover to the fiberglass pipe insulation. (Cold Water, Chilled Liquid, etc)
3.) Use Proto One PVC Adhesive  or Permaweld to glue the seams of the fitting cover. (Exterior Piping, USDA, Washdown Area, etc)
*Tacks, Vinyl Tape, and Adhesive are sold separately.

    The PVC pipe covers look so much neater and cleaner than the old method! Makes the basement room feel clean and finished. Quick and easy to install. I'll be purchasing more for the rest of the basement.

    I overlooked all 4 of the unions the pipes had in my basement when first placing my order. Once I started popping the insulation sticks on the pipes I found that all these unions were too big to go over. I spoke to a very helpful gentleman who walked me through all my options and recommended the union covers since they were the easiest option I had. I am glad I took his recommendation as they were easy to install and look great.

    Only did a couple, but they were easy to install, and the result looks good.

    *Roger, a union cover gives the finishing touch to a pipe insulation project. Glad your project came out as planned! ~ BIP

    The PVC covers are a great companion to the pipe wrap. Learned to trim with sharp scissors for a tight fit. The push pins are sharp and effective.

    This adds a nice finished look to the piping system. I used pop rivets to secure it.

    Nice Afforable Product

    Comes with a piece of insulation to stuff inside the PVC. Very affordable and looks sharp. Get a roll of ASJ Tape, it comes in handy.
